Do these still have the issue with leaking or did they get that taken care of?

Mine leaked. It is not just the design of the shifter, more the design of the trans. The vent for the trans is located in the factory shifter. The Hurst does not incorporate that in.

If you have any issues with it, there is a good HOW TO on RPS, to fix it. It is pretty much replacing the gasket, and cutting in a "vent". I had to do it to mine, and besides a little weeping, there is no visible signs of it leaking.

Theyve gotta breathe. Stock breather is taken out when the Hurst is installed, because its located on the pivot assy. No breather = pressure buildup, oil pushes through the weakest point, thus making what appears to be a leak.

I haven't had a problem with leaking so far but I drilled and tapped a hole into the side of the circular mounting plate. Threaded in a small fitting. Some plastic or high temp tube routed up into the engine compartment. Just push the tube into the fitting and it locked. Squeeze the fitting and pull it out. Looks pretty good.
